Amazon.com Inc, the Web retailer known for selling books, said it had paid about $4 million to buy a handwritten, illustrated book of wizardry by “Harry Potter” author J.K. Rowling.

Sotheby’s on Thursday held an auction for the book called “The Tales of Beedle the Bard,” which was mentioned in the last Potter book as having been left to Harry’s friend Hermione by their teacher, Albus Dumbledore.

There are just seven copies of “The Tales,” bound in brown Moroccan leather and decorated in silver and moonstones. Rowling gave six copies of the book to people closely connected to the Harry Potter books and auctioned off the seventh.

OK, so the money goes to charity which is great, but even though it will likely never be published, you can see the $4,000,000 book by clicking here.
